Background: Our goal is to examine the association of recurrent aphthous stomatitis (RAS) with symptoms of depression using a smartphone-based questionnaire survey.
Methods: An electronic survey was administered through a smartphone app asking respondents about current depressive symptoms using the Quick Inventory of Depressive Symptoms (QIDS), and asking whether they had ever or recently experienced RAS. Multivariate logistic regression analysis was used to determine associations.
Aim: To estimate the prevalence and risk factors for vitreous floaters in the general population.
Methods: An electronic survey was administered through a smartphone app asking various demographic and health questions, including whether users experience floaters in their field of vision. Multivariate logistic regression analysis was used to determine risk factors.
